Allegiant Air started up the new nonstop flights between Phoenix and Bozeman in November, just in time for the ski season. The new flights operate twice each week on Mondays and Fridays.

Flights depart the Phoenix-Mesa Gateway Airport (IWA) at 2:40 p.m. and arrive in Bozeman at 4:50 p.m. Returning flights leave Gallatin Field Airport (BZN) in Bozeman at 5:30 p.m. and reach Phoenix at 7:55 p.m. The timing of the return flights works to spend a chunk of the day on the slopes before heading to the airport.

Allegiant Air is known for its low-cost flights. Regular one-way fares on the Bozeman-Phoenix route start at $65.

Airport shuttle services are available to get to Big Sky and Moonlight Basin, neighbors sharing terrain with the Biggest Skiing in America joint lift ticket. The shuttles, which take less than one hour, let someone else do the winter driving through the narrow, curvy Gallatin Canyon. Those planning to ski Bridger Bowl should rent a car instead.

Big Sky Central Reservations can book flights from Phoenix to Bozeman for Allegiant as well as set up lodging and lift ticket packages. Visitors heading to Moonlight Basin or Bridger Bowl will need to book airfare through Allegiant, but can make reservations for lodging and lift ticket packages through the resorts. Moonlight's lodging is handled by East West Resorts. Lodging for skiing Bridger Bowl is in downtown Bozeman, about 20 minutes from the ski area.
